In the 1st century A.D., two long aqueducts were built to supply the city with water.
The first was fed by the Gai√† river and was approximately 40 km long. The second was fed by the Francol√≠ river and was some 15 km long. The most spectacular surviving stretch belongs to the second aqueduct and consist of a 217-metre segment that stands 26 metres tall at its highest point and bridges a ravine.
It was built from large ashlars stacked without mortar to form two tiers at arches. It is popularly known as the Pont del Diable (Devil‚Äôs Bridge) or the ‚ÄúLes Ferreres‚ÄĚ Aqueduct.
